I am having serious problems with my Intel(R) Dual Band Wireless-AC 8260.
I have many connectivity issues at my network: wifi shuts, unable to connect, slow speeds (less than 10Mb), hyper slow (less than 1Mb). That wifi router works fine with many other devices. So it is not the router device.
What I tryed:
Get in touch with the manufacturer and install the latest recommended drivers for my ASUS ZenBook Flip S UX370UA
(UX370UAF bios and W10 64 system):
https://www.asus.com/es/2-in-1-PCs/ASUS-ZenBook-Flip-S-UX370UA/HelpDesk_Download/
https://dlcdnets.asus.com/pub/ASUS/nb/DriversForWin10/WLAN/WLAN_Intel_Win10_64_VER201022.zip
Then I followed the steps:
- download driver
- uninstall proset and old driver if still remains
- reinstall manufacturer recommended driver
The problem is still there. But manufacter driver says 20.10.2.2 but device manager still says 20.50.0.5!!!!
It seems that I am not able fully uninstall "newer driver"
I have read somewhere these file may still be there and prevent the right installation.
c:\windows\system32\drivers\netwfw06.dat
c:\windows\system32\drivers\netwtw06.sys
c:\windows\system32\drivers\vwifibus.sys
c:\windows\system32\IntelWifilhv06.dll
I am scared to uninstall them and to "brick" my computer
Any ideas?
Thanks and best regards

And also a procedure to prevent W10 to intall the driver by itself.
Have I to manage oem48.inf file?
Any Ideas? Thanks

To stop windows 10 installing drivers, go to control panel, large icons, devices and printers, right click on your computer, device installation settings, NO.

I have tried it once. No luck
I will try again.
That would make other devices not updatable. wouldn't it?

No Luck
Even with that option on, it reinstalls by itself to version 20.50.0.5

To uninstall fully, do the following:
- Download the latest Wireless and Bluetooth packages from the Intel Download Center..
- Disconnect the laptop from the Internet (unplug Ethernet and disable Wireless).
- From the Apps & Features applet, uninstall the existing Intel Wireless and Bluetooth packages.
- Reboot, keeping laptop disconnected from Internet.
- Open the Device Manager applet and expand the Networking Adapters section.
- If there is no entry for the wireless card, go to step 9.
- Right-click on this entry and select Uninstall Device.
- Go back to step 4.
- Install the Bluetooth package you downloaded earlier.
- Install the Wireless package you downloaded earlier.
- Reboot.
- Reconnect Internet.
- Test.
Hope this helps,

I forgot to add, you can substitute earlier packages in place of the latest, but remember that, in this case, Windows Update could upgrade the drivers automatically, so you need to disable it.

The OP says that even with it turned off, the update gets installed.
@ESuel Do you have some ASUS support assistant running?

"Maybe ASUS updater is doing some harm updating things"
If you have blocked windows driver updates like I said, and you are not installing with IDSA, then I would say Asus updater is your problem.

Many many thanks Al.Hill (aka Doc) and n.scott.pearson for your help
I had some mild COVID19 symptoms and was not physically in shape until now to try your solutions
Windows kept updating BUT.... (half) GOOD NEWS
A newer driver was installed by Windows Update (or was it me updating in device manager? My mind is still fuzzy):
Intel(R) Dual Band Wireless-AC 8260
20.70.13.2
It is a huge improvement from null/ shitty to poor performance (not a joke)
Before:
Many times random wifi shut downs. Some times continuously
When not shut down, most of the times less than 1Mb/s
Some times something between 5 and 10Mb/s. Hopefully I could download the updates!!!
(Issues above happened at home wifi network. It worked fine in some wifi networks)
Now:
Now wifi does not shut down randomly almost all the time. Just less than 5 of times in 2 hours.
And it gets about 20Mb/s (this is new) or 10Mb/s or 5Mb/s or 0.5Mb/s (sigh, but not many times)
(I hope it still works in the office after the version upgrade. I will know after confinement)
There is still something funny in the driver.
I wish the next update comes with a solution for all the problems and doesn't mess around and returns to the inability to use some wifi networks.
And the tree parties don't blame on each other (MS, Intel and OEM in my case ASUS)
Do you know if there is a way to send Intel developers these issues? (so they can check the driver)
My expectations in this are low

You may also be seeing lower numbers because of the Internet saturation that is occurring because everyone is isolating themselves over COVID-19.

Other devices are running between 25Mb/s and 60Mb/s
Definitely it is some problem in device / system / driver (some or all of them)
All the posts published about this wifi adapter make me think something funny happens with it.
Cheers. And stay at home as much as possible

Hi I have been playing around with adapter advanced options (under W10 device manager)
When I change some settings the wifi thourghoutput speed boosts.
The settings I am fiddling with are: 802.11 modes, power, bandwidth, roaming.
But after a while things corrupt from 25Mb/s speeds (Comparable to other devices at home) to 1Mb/s-5Mb/s (or worse)
No luck

Hello ESuel
Thank you for posting in the Intel Community.
1. Are you using the same tool to evaluate the network speed on all the devices?
2. Have you tried restating the systems on the environment (laptops, router)?
3. can you try the Advanced Intel® Wireless Adapter Settings to manipulate setting like:
a. 802.11n/ac/ax Wireless Mode or HT Mode
b. Channel width or 802.11n channel width (band 2.4/5GHz)
4. You can also try Clean Installation of Wireless Drivers with both OEM and intel drivers.

Answers
1. Are you using the same tool to evaluate the network speed on all the devices?
I am using Google and ISP speed-o-meters
Difference is too high
Some devices take 30-40Mb/s
Computer with troublesome adapter takes some times 20-25Mb/s (not many times), 3-10Mb/s (quite often) and below 1Mb/s or continuous cuts (very often)
As I write, I get 0.27Mb/s (sigh)
2. Have you tried restating the systems on the environment (laptops, router)?
Yes. Too many times
3. can you try the Advanced Intel® Wireless Adapter Settings to manipulate setting like:
a. 802.11n/ac/ax Wireless Mode or HT Mode
b. Channel width or 802.11n channel width (band 2.4/5GHz)
Yes. I have changed things like:
-Mode 802.11 a/b/g
-Mode 802.11 n/ac
-Bandwidth for 2.4GHz
-Roaming
-Power
After the setting change, some combinations had speed over 25Mb/s or even up to 35Mb/s
But after some time (hours) performance started to go down: then about 10Mb/s, then about 0.5Mb/s and continuos cuts
And fiddling with settings doesn't help anymore
It is like something in the driver or the device erodes over time degrading performance as time goes by.
4. You can also try Clean Installation of Wireless Drivers with both OEM and intel drivers.
Yes I tried with OEM and Intel's
Right now I have latest available driver from Intel
I suspect when I uninstall, some files are not being erased (and maybe others aren't as well)
Such as:
c:\windows\system32\drivers\netwfw06.dat
c:\windows\system32\drivers\netwtw06.sys
When I look at my router log some times I can see 10 or 50 disconnections and reconnection cycles (one example)

Hello ESuel
Thank you for the details, please provide me the following details:
1- when did the issue start?
2- It's a brand-new system?
3- It was working fine previously?
4- Can you try a wired connection just for testing?
5- Is this the wireless that came preinstalled on the system or did you change it?

Here is the info
Cable OK
5GHz OK
2.4GHz KO (it starts fast and then degrades)
1- when did the issue start? From the beggining. But I was not aware about the reason of the problem. First I thought it was the router
2- It's a brand-new system? It was a band new system when the problem started
3- It was working fine previously? It only worked fine the first moments after factory reset or driver upgrade. it took short time for speed and connectivity (2.4GHz) to degrade
4- Can you try a wired connection just for testing? Yes. It goes full throttle 600Mb/s
5- Is this the wireless that came preinstalled on the system or did you change it? It is not the preinsalled.
I tried the driver from ASUS, but it doesn't work.
Now it is the latest version at Intel's site. version 20.70.16.4 for Intel(R) dual band wireless AC-8260
I haven't tried an older driver from ASUS yet
I am afraid when uninstalling there maybe are some unerased files or configs.
How can I prevent any interference of those uninstalled files / configs? If they exist
HW
Last year, I took the laptop to the manufacturer: they did a fresh install, they say that they did some tests and they say it was ok
I don't know if they tested the 2.4GHz band
Many many thanks
